SPECIFICATION forming partof Letters Patent No. 384,831,6.ated June 19, 1888.

Application tiled December 152, 1887. Serial No. 257,670. (No model.)

To all whom it may concern:

Beit known that I, JOHN EINIG, a citizen of the United States, residingin Jacksonville, county of Duval, and State of Florida, have invented certain new and useful'lmprovements in Alarms for Elevators, of which the following is a full, clear, and exact specification.

My invention relates to a device for giving alarm when the elevator is in motion while going up and down, as maybe desired, the object of which being to signal to or notify any person who may be standing in the well or shaft that the elevator is descending and that they are in danger of being injured.

My invention consists in mounting a rotatable shaft upon any convenient part of the elevator-car,with a bell secured to one end thereof and a grooved wheel to the other, and pro` viding a hearing-surface from top to bottom of the elevator-shaft with which said wheel engages, so as to revolve it and the shaft, and consequently sound the bell when the elevator is in motion.

Myinvention will be more fully understood lby the following description with reference to the accompanying drawings, to Wit:

Figure l is a vertical sectional View of an elevator having my improved alarm appended to its bottom.` Figi 2 is an enlarged detail view.

l represents the sills upon which the floor or platform ofthe elevator rests. Secured to the under side of two of these sills are brackets 2 3, each of which supports a journal-bear: ing, 4, through which bearings projects the rotatable shaft 5, having lugs or.collars 6 7 for thevpurpose of preventing longitudinal movement of the former.

Bolted transversely to the inner end of the shaft`5 is an ordinary bell, 8, which is provided with the usual loose clapper, and jour- `naled loosely on the outer end of said shaft is a grooved frictionwheel, 9. Secured to the shaft, however, and in juxtapositionv to the wheel 9, is a ratchetwheel, 10, which is engaged by a pawl, 11, pivoted to the former wheel. A cord or cable, 12, which serves as the vertical bearingsurface for the grooved frictionwheel, is passed once around the latter and is stretched from top to bottom of the elevater-shaft for the purpose of engaging the periphery of said wheel, whereby when the elevator is put in motion the wheel 9 will re` volve by virtue of its frictional contact with the cord; but by reason of its only having power to revolve the shaft through the mediurn of the paw] and ratchet the bell will only be sounded when the elevator is descending, or, if desired, when ascending. This bell could of course be made to ring while the .ele-` vator moved up and down, also, by merely keying the wheel 9 to the' shaft; but this will be seldom found to be necessary.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. The combination, with an elevator-car, of

an alarm secured thereto, ashaft for operating k wheel and stretched vertically in the elevatorshaft, substantially as set forth.

3. The combinatiomwith the elevator-car, of l a rotatable shaft journaled thereto, a bell on said shaft, a friction-wheel journaled loosely on said shaft, a perpendicular cord with which. said wheel engages, and a pawl and ratchet secured to said shaft and wheel, respectively,

whereby the shaft is revolved in one direction only, substantially as set forth.

JOHN EINIG.
